In order to track how cities develop and grow, multidimensional systems of urban development indicators taking into account the balance between economic, social, and environmental aspects are the best solution found so far. However, there is no unique measurement system that would be widely accepted and applied within various urban areas to verify whether a given city is developing in a sustainable way. The aim of this paper is to apply the topsis algorithm on the basis of selected urban indicators, in order to evaluate the progress of a single city towards the concept of sustainable development observed over a longer period of time. A capital city of Poland, Warsaw, faces several challenges associated with development policy evaluation, thus confirming the need for this research. We meticulously selected 48 indicators from the economic, social and environmental areas as an input for topsis algorithm, which allowed us to calculate a new proposed aggregated index for evaluating urban policy on the example of Warsaw. Research has shown usefulness of applied topsis algorithm in assessing the long-run development of an urban area towards the concept of a sustainable city. The results of our analysis indicated that over a period of ten years, during 2008-2017, the urban policy decision-making has been balancing the socio-economic and environmental aspects and the city of Warsaw has been developed in a sustainable manner.

Small, medium and micro enterprises are an important force in my country's economic and social development. On the one hand, development creates regional GDP and on the other hand provides a large number of employment opportunities. At present, most of the small, medium and micro enterprises have their own imperfect development, and there are problems such as small business scale, irregular management, and information asymmetry. To avoid risks, commercial banks do not actively provide loans for small, medium and micro enterprises. Small, medium and micro enterprises have long faced financing difficulties. The problem. This article first uses data processing software to classify and summarize the credit data of 123 companies with credit records, establishes 10 quantitative indicators represented by reputation risk level and default risk level, and classifies and visualizes each impact indicator, to find out the correlation between the indicators. Furthermore, based on the analysis results of the indicators, a mathematical model of the multidimensional scaling algorithm among the 10 indicators is established, and the deep correlation classification of the indicators among the enterprises is analyzed.

In order to improve the performance of the fault diagnosis algorithm under the carrier network, this paper proposes a carrier network fault diagnosis algorithm based on service characteristics. First, in order to use business characteristics for fault diagnosis, this paper calculates the three characteristics of the certainty of failure of each network node, historical failure performance, and resource utilization, and uses the topsis algorithm to calculate the failure probability of the network nodes in the network node set. Secondly, according to the abnormal credibility of the abnormal business, sort the symptoms in the abnormal symptom set in descending order. Finally, fault location is performed according to the importance of the business and the reliability characteristics of network node faults. In the experimental part, the algorithm in this paper is compared with the existing algorithms, and it is verified that the algorithm in this paper can improve the accuracy of the fault diagnosis algorithm and reduce the false alarm rate of the fault diagnosis algorithm.

Mimic defense is an active defense theory, which aims to fundamentally change the "easy to attack and difficult to defend" situation of network security. In this paper, we propose an evaluation method based on the probability of being attack successfully, and improve the evaluation scheme of historical confidence. We combine the two evaluation schemes with the topsis (technique for order performance by similarity to ideal solution) algorithm, and finally form a complete heterogeneous variant dynamic scheduling model. Different from traditional multi-mode voting algorithms, the effect of the heterogeneous degree in voting is considered, and we use Bayesian estimation to obtain the optimal result in the probabilistic sense. Finally, simulation results show that the proposed algorithm can effectively enhance the dynamic and security of the mimic defense model, and give full play to the characteristics of mimic defense.

With the rapid development of modern teaching technology, the construction of smart campus has become the focus of modern college education reform. The application of technologies, such as the Internet of Things and big data, plays an important role in improving the teaching environment of colleges and universities, improving the utilization of teaching resources, and the flexibility of education. As an important part of campus activities, teaching performance evaluation scientifically and effectively utilizes teaching information and teacher and student interaction information to evaluate teachers' teaching performance, which helps to motivate teachers' work enthusiasm, improve teaching quality, and enhance school core competitiveness. This paper analyzes the salient features of smart campus from the perspectives of technology, business, and construction mode, and proposes a smart campus architecture model. According to the research content of teaching performance evaluation, the framework model of smart campus education data collection and storage platform is established, which provides a reference model for the construction of smart campus in colleges and universities. The evaluation of teaching performance in smart campus first analyzes the shortcomings of traditional evaluation methods and proposes the necessity of combining teaching performance evaluation with modern technology. Second, six principal components were determined using the PCA algorithm. Then, use the AHP to calculate the weights of each layer of the indicator set, avoiding the decision errors caused by subjective factors. Finally, the gray correlation degree is used to improve the topsis algorithm for multi-objective decision analysis. The evaluation results of the AHP-topsis teaching performance model are consistent with the actual situation. The application of the smart campus education data platform combined with the AHP and the gray correlation improvement topsis algorithm is more targeted t

In this paper, for the defects which the basic genetic algorithm can get local optimum easily and converge slowly, the genetic algorithm is improved by constructing a suitable fitness function and improving genetic operators. Meanwhile, the improved genetic algorithm is applied to select optimal access network in integrated heterogeneous wireless networks. According to Quality of Service (QoS) requirements of different business types, compared with combined the analytic hierarchy process (AHP) and the technique for order preference by similarity to an ideal solution (topsis) and the basic genetic algorithm, the simulation results indicate that the improved genetic algorithm can find a network with higher fitness and better meet different QoS.

Football is one of the most popular sports in the world. Professional football has become a significant contributor to global economics and business. The game attracts considerable funds, which motivate participants of the sporting process (players, coaches, club owners, administration, etc.) to strive for better athletic results. However, such a motivation simultaneously promotes internal and external rivalry. The increasing number of players, the teams' desire to attract better team members, and the improved athletes' performance boost the use of assessment and rating processes. The most popular and widely used player rating systems are based on performance statistics, which reflect situational factors of the game. Most specialists believe that such systems lack objectivity. Thus, this paper presents a new methodology to assess and rank football players based on multi-criteria decision making (MCDM). A hands-on study is conducted for the assessment. A sample of 24 players is grouped into four separate groups consisting of six players for each group. The age of U17 is examined by 12 tests distributed as follows: three anthropometrics, five fitness, and four skills tests. Players are ranked on the basis of a set of measurement metric outcomes using the technique for order performance by similarity to ideal solution (topsis) method to select the appropriate player using a one-shot experiment. Then, this study utilizes the mean and standard deviation to ensure that the four groups of players undergo systematic ranking, respectively. Findings are as follows: (1) systematic: topsis is an effective tool used to solve player selection problems, and (2) statistics: group number one is the best group among the four groups, identical to the results of the system.

With the development of wireless communication technology, Internet users have higher requirements for QoS (Quality of Service) in wireless networks. The choice of feasible routing paths is inevitable in order to meet demand for services. As we know, in wireless environment the network status usually changes frequently and rapidly. hi this thesis, we propose a QoS routing algorithm based on Vague Set theory to eliminate the impact of this adverse factor. The experiment implemented in the end proves the effectiveness of our algorithm.
